Abstract
The invention discloses a kind of dual-beam precinct laser fusion increasing material manufacturing methods, it is one in front and one in back printed by dual-beam, first laser melts powder outer profile to low power fine, second laser is scanned to carry out the Fast Filling of high power large spot, by two beam laser collective effects, so that it carries out selective laser melting (SLM) molding, powder forming precision had both been improved, the rate of forming is also improved, the efficiency of precinct laser forming can be significantly improved.
Description
Technical field
The present invention relates to increases material manufacturing technology field more particularly to a kind of dual-beam precinct laser fusion increasing material manufacturing sides
Method.
Background technique
Increasing material manufacturing is to have merged CAD, material processing and forming technique, using digital model file as base
Plinth according to extruding, is burnt by software and digital control system by dedicated metal material, nonmetallic materials and biomaterial for medical purpose
The modes such as knot, melting, photocuring, injection are successively accumulated, and the manufacturing technology of physical item is produced.And selective laser melting process
It is the increases material manufacturing technology to metal powder, it is completely melt, through cooling solidifying under the heat effect of laser beam using metal powder
Gu and a kind of molding technology.Wherein, powdering formula selective laser melting process is that current more mature, main metal 3D is beaten
One of print technology.When processing, the uniform shakedown layer of material powder in processing plane, powder thickness is often according to processing technology
It determines.Thereafter, control system control laser export laser, via galvanometer on bisque scanning machining figure.Portion after scanning
Point melt, after entity is solidified as together with the part below bisque again, and rest part is still pulverulence.By with
Powder bed is constantly melted, is solidified from level to level, is gradually superimposed, is finally configured to required product.
As a kind of emerging advanced manufacturing technology, selective laser smelting technology is developed so far, and it is intrinsic also to expose itself
Defect: forming efficiency is low, forming accuracy can not be compared with traditional processing mode, suitable material is limited, consistency is unable to reach
100%, the internal flaws such as stomata, crackle can not avoid completely, and skill is melted in especially this low limitation selective laser of forming efficiency
Art obtains the bottleneck further developed.During single laser beam selective melting, can only successively it be scanned after every layer of path planning, it is this
" serial " processing method causes many residual paths to be in " waiting period ".In addition, forming efficiency and dimensional accuracy are conflicts
Body usually improves laser power and spot size, but reduces precision to a certain extent to obtain higher forming efficiency,
Especially marginal dimension precision.And in order to obtain finer part, it usually needs reduce spot size and reduces its power, visitor
Monolithic molding efficiency is reduced in sight.
Existing SLM technology is not able to satisfy Modern Manufacturing Technology temporarily and makes to efficient, high-precision, high quality, high speed
The demand made, so that the application range of SLM metallic print is only capable of being confined on the components of small size.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of dual-beam for defect involved in background technique
Precinct laser fusion increasing material manufacturing method.
The present invention uses following technical scheme to solve above-mentioned technical problem:
A kind of dual-beam precinct laser fusion increasing material manufacturing method, includes the following steps:
Step 1) pre-processes shaping substrate, after cleaning, drying, is fixed on the intracorporal workbench of work box；
Step 2 carries out gas washing processing to argon gas is passed through in working box, reduces the oxygen content in working box, and heat the substrate
To reach printing required temperature；
Step 3) is layered the model printed, beats in accordance with the following steps each layer from the bottom to top
Print:
Step 3.1) carries out powdering to substrate；
The printer model of current layer is decomposed into and needs to carry out outer profile part and outer profile that fine fusing increases material by step 3.2)
The part to be filled of partial interior；
Step 3.3), while being worked using first laser device and second laser, the operation light spot of first laser device is less than
The hot spot of second laser, wherein fine fusing is carried out using the external outline portion of the hot spot of first laser device and increases material, using the
Dual-laser device carries out high-power Fast Filling processing to band fill part.
When carrying out powdering in the step 3.1), powdering thickness is 0.05mm.
The first laser device, the maximum power of second laser are 800W.
